TIRE-CASING.

SPECIFICATION forming part of Letters Patent No. 782,912, dated February21, 1905.

Application filed February 23, 1904. Serial No. 194,804.

To r/JZ whom it may concern:

Be it known that 1, JOHN 0. KING, a citizen of the United States, and aresident of Racine, in the county of Racine and State of Wisconsin, haveinvented certain new and useful Improvements in Tire-Casings; and I dohereby declare that the following is a full, clear, and exactdescription thereof.

My invention has especial reference to a casing for pneumatic tires, thesame being of the general style known as clenchers, and it consists incertain peculiarities of construction and combination of parts, as willbe fully set forth hereinafter in connection with the accompanyingdrawings and subsequently claimed.

In the said drawings, Figure 1 is a perspective View and partly asectional view of a portion of my said tire-casing. Fig. 2 isa view inside elevation of the entire tire-casing, drawn to a greatly-reducedscale. Fig. 3 is a detail view showing the lap of two parts of thecasing, taken on the plane indicated by the line 3 3 in Fig. 2, butdrawn to the same scale as Fig. 1.

Referring by numerals to the drawings, 1 1 represent the sections ofwhich my tire-casing is formed, four of such being here shown, but theexact number being immaterial. These sections are made of any suitableflexible leather, the edges of each two adjacent sections being skived,as shown at 3 3 in Fig. 3, and when put together secured by lines ofstitching 2 2, so that the uniformity of the surface of these leathersections is not disturbed, both the inner and outer surfaces being atall points smooth and the leather sections everywhere of equalthickness.

The casing adjacent to its inner periphery is doubled at each edge, asshown at 4 4, the thus doubled parts being held together by rows ofstitching 5 5 to form the projecting edges whereby the said tire-casingis held to the clencher-rim, the latter being indicated by. dottedoutline at 6 in Fig. 1, and beyond these folded edges 4 4 the leather ofthe casing is continued from each side to about the center, where theedges are skived and overlapped, as shown at 7 7, but are not fastenedtogether, being left open for the admission of the pneumatic tire ortube, (indicated by the dotted circle marked 8 in Fig. 1,) which wheninflated fills the said tire-casing and keeps same firmly locked inproper position on and in the rim.

In order to insure a rounded interior surface to the casing and preventthe inflated tire or tube from being forced against the inner angle ofthe doubled edges 4 4, which would soon destroy or greatly injure thesaid inflated tire or tube, these angular spaces are filled up by theannular leather strips 9 of an approximately triangular shape incross-section, and these strips are secured to the tiresections 1, as bythe lines of stitching 10.

The tread of my tire-casing is formed of a continuous strip orsuccessive strips of soleleather, (marked 11,) secured in any suitableway to the outer circumference of the casing, but preferably by thesplit rivets 12 12, as shown, as these not only secure the casing andits tread firmly together, but greatly aid in making the latterpuncture-proof.

My tire-casing by being made all of leather is much more durable thanone made of rul ber or rubber-and-fabric compounds, and if it everbecomes necessary to repair same this can be more readily, cheaply, andsuccessfully done than with rubber casings, and I produce an altogetherbetter and stronger device particularly adapted for use with automobilesand in heavy teaming.

If desired, my casing when completed as herein described may be linedwith any suitable fabric, secured by rubber cement to the inner surfaceof said casing, as indicated at 13, the said lining extendingcontinuously to theinner edges of the central annular opening, and hencecovering up the described filling-strips 9, but not interfering withopening of the casing when the pneumatic tire or tube 8 is to beinserted or removed.

The leather of the sections 1 1 may be waterproofed in any preferredmanner either before the completion of the casing or afterward.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A tire-casing, comprising sections of flexible leather stitched togetherto form a continuous annular tube open at its inner circumference, andwith the meeting edges there, and at the junction of each two sectionsskived to insure uniformity of surface and thickness at all points ofunion, and with the leather of the sections folded and stitched togetheron each side of the line of the annular opening,

in combination with annular angular strips filling the angular spacesback of the said folded portions, and rows of stitching uniting saidstrips to said casing.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of VVisconsin, in thepresence of two witnesses.
